difference between speed and lvelocity in three point
Explanation:
(1)speed is scalar quantity
(1) velocity is vector quantity
(2)speed can never be negative or zero and it is always positive
(2) velocity can be negative or zero and it can be positive
(3)speed is time taken to travel a specific distance
(3) velocity is time taken to travel minimum distance from 1 point to other point
(4)speed=distance upon time
(4) velocity = displacement (minimum distance between 2 points ) upon time

A student wants to find out if the green coloring in grass is a mixture of dyes. He uses a solvent to dissolve the green coloring from some grass. He then separates the solution of the green coloring from the remaining grass. Which of these methods is used to separate the solution of the green coloring from the remaining grass?Immersive Reader (1 Point) Boiling Evaporation Chromatography Filtration
Answer:
The correct answer is - filtration.
Explanation:
Filtration is the extracting the dissolved or suspended solids from a liquid or solvent passed from a substance with small pores, called filter, that separates the solid with a larger size than the pores of the filter. The liquid goes through the filter known as filtrate.
In the given case, the remaining grass can be separated from the solvent by the process of filtration. Pass the remaining grass with filtrate through the filter.
The correct answer is - filtration.

Describe two types of evidence–other than the comparison of DNA sequences–that can be used to determine the phylogeny of organisms. Discuss one strength of each type of evidence you described.
Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related

The nitrogen cycle is an example of a(n) (blank) cycle. The options are biogeochemical, decomposer, energy, water, denitrification, nitrogen fixation, nitrogen limitation, or photosynthesis.
Answer: Biogeochemical, Nitrogen Fixation, and Denitrification
Explanation: A biogeochemical cycle is the cycling of a nutrient through the biosphere and the geosphere. Nitrogen fixation happens when Nitrogen Fixating bacteria take in atmospheric nitrogen and release Ammonia as a biproduct. Denitrifying bacteria then take in the ammonia and break it down into nitrite, nitrate, and finally back into atmospheric nitrogen. The cycle then repeats.
The nitrogen cycle is an example of a biogeochemical cycle. The correct option is A.
What is biogeochemical cycle?The transport and transformation of chemicals in ecosystems is referred to as a biochemical cycle. Wetland hydrologic conditions have a strong influence on these.
These processes cause changes in the chemical forms of materials as well as material movement within wetlands.
These cycles transport the elements required for life to survive throughout the ecosystem.
They are essential because they recycle and store elements, as well as regulate vital elements through physical facets.
A biogeochemical cycle describes how an element or compound, such as water, moves between its various living and nonliving forms and locations in the biosphere.
Water, carbon, nitrogen, phosphorus, and sulfur cycles are all important biogeochemical cycles for living organisms.
Thus, the correct option is A.

How do enzymes affect the reactions in which they take part?
A.Most enzymes slow down chemical reactions.
B.Enzymes decrease the activation energy of the reaction.
C.Enzymes increase the activation energy of the reaction.
D.Enzymes are converted into products in the reaction.
Answer:
B. Enzymes decrease the activation energy of the reaction :)
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
5. Which of the following are enzymes?
1 point
Lipase
Lactose
Amylase
Xylase
Cellulose
Glucose
Fructase
Fructose
Lactase
NONE OF THESE!!!
Answer:
Lipases, Amylase, Lactase, and Cellulase. Did this Help?
Explanation:
Lipases – a group of enzymes that help digest fats in the gut.
Amylase – helps change starches into sugars. Amylase is found in saliva.
Maltase – also found in saliva; breaks the sugar maltose into glucose. Maltose is found in foods such as potatoes, pasta, and beer.
Trypsin – found in the small intestine, breaks proteins down into amino acids.
Lactase – also found in the small intestine, breaks lactose, the sugar in milk, into glucose and galactose.
Acetylcholinesterase – breaks down the neurotransmitter acetylcholine in nerves and muscles.
Helicase – unravels DNA.
DNA polymerase – synthesize DNA from deoxyribonucleotides.
Cellulase -- is any of several enzymes produced chiefly by fungi, bacteria, and protozoans

Answer:
A. 2
Explanation:
I was wrong the first time, I wasn't thinking of jupiter for some reason. sorry!
Answer:
A. 2
Explanation:
Jupiter's magnetic field is quite different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature study finds. Scientists analyzed Jupiter with NASA's Juno spacecraft, which reached the planet sometime in 2016.

Explain why heavy fertilizer runoff and algal blooms disrupt the equilibrium (balance) in an aquatic system.
A. Fertilizer runoff:
B. Algal blooms:
Answer:
A - Fertilizer runoff can cause micro-organisms such algae to bloom out of control. B - Algae blooms suffocate the ecosystem if there is too much.
Explanation:
A - Not all fertilizer nutrients is used in agricultural production and so some of it makes its way into the excess water and therefore runs into creeks and rivers. It is also toxic to many animals in high concentrations as well as more sensitive native plants.
B - Algae blooms take a lot of oxygen out of the water, therefore suffocating natural wildlife. The decay that results from such large blooms is also problematic and takes away oxygen. Many algae likes slow moving water with little flow and in these optimal conditions with excess nutrients (Nitrogen, Phosphorus, and Potassium, NPK are the main ones) cause it to become out of control
